Extracted Audio
The extracted audio ports have three distinct operating modes. Your desired mode can be set to suite your
particular installation.
The 3 modes are:
Bind to Input ~ This is the default configuration. In this mode the audio port number corresponds to the
INPUT signal. This is ideal for systems where audio is matrixed separately in a zoned amplifier.
Bind to Output ~ This configuration will automatically have the audio follow OUTPUT, so the audio from
the extracted port always matches the HDMI output. This is ideal for systems that use local AVR’s for some
of the zones.
Independent/Matrix ~ This mode allows you matrix the extracted audio outputs independent of HDMI.
In this mode a new set of commands becomes available to be able to route audio however you want. This
can be used as a separate zoned audio matrix with only using an amplifier.
Setting up Extracted Audio Routing:
You can set up Extracted Audio Routing from the front panel, WebUI, Driver or by sending the following
command:
SET EXAMX MODEx -- Where {x=[0~2](0=Bind To Output,1=Bind To Input,2=Matrix}
If you set to “Matrix” you can use the following command to route the 16 extracted audio ports to any
INPUT:
SET OUTx AS INy -- Where Set Ex-Audio Output x To Input y{x=[0~4](0=ALL), y=[1~4]}
Balanced 5 pin 2Ch and Toslink Audio Port /SPDIF:
The SPDIF Toslink port supports up to 5.1 Ch Digital audio the balanced 5 pin terminal connector supports
2 Ch audio only. This means in order for these ports to function the sources must be set to 2 Ch PCM, this
unit does NOT down mix the audio (see AC-AXION-4 for down-mixing matrix). To get more than 2 Channels
you will want to use the SPDIF port.
